Tips on centering rear end? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Any good tips on centering the rear diff? I have installed a set of 3" drop springs and will probably get a set of 2" blocks to finish it off. With that much drop I'll need to get an adjustable panhard bar as well. And I'll need to get it all lined up correctly so as not to tear up my carrier bearing... Which may be part of my issue now with a new vibration. Also how much of a pinon shim will I need with a total of 5" of drop? Any help appreciated!

On centering the rear end; With the weight on the tires, measure from the frame rail to the brake backing plate, in the same place on each side. Then use a ratchet strap attached to the rear end & frame to pull it over until distance on each side is equal. Adjust panhard bar, and install.

I did plagerize this from another thread. But I did mine this way and it worked fine. So credit goes to the original author, whoever they are.

I dunno about the pinion angle.

I measured mine the same way but just pulled the body over and hooked in the adjustable sway bar once I had it set correctly.
